So the person believes that their interpretation of the Bible is infallible - and everyone else who disagrees with him is wrong. And every other Christian, Muslim and Jew thinks it is they who are right!

Of course it is a logical fallacy and a gross statistical error to interpret the data after the fact to conform to one's pet theory. The fact that this guy thinks it is perfectly O.K. is testimony to the extreme methods that someone will use to delude themselves into thinking that their preferred or indoctrinated belief system MUST be correct. We are irrational animals when we are listening to emotions.
